." CAN-WIPING MACHINE.

SPECIFICATION forming part of Letters Patent No. 416,212, dated December 3, 1889.

Application tiled March 11, 1889.

To all whom it may concern.- 1 Be it known that I, PERLEY D. a citizen of the United CUMMINGS, States,residing at of Cumberland and State of Maine, have invented certain new and useful Improvements in Can-\Vipin Machines; and I do herebydeclare the following to be a full, clear, and exact description of the invention, such as will enable others My invention relates to machines for wipin g the tops of cans in the operation of packing corn and other like substances.

The object of my invention isto construct a wiping-machine which shall remove all the moisture from the top' of the can,and particularly fromthegroove or channel which surrounds the mouth of the can and in which the edge of thecap fits.

The several features of my machine are as set and a lever for lifting "it against the wiper, a rotating fly-fraine.:having wipingrolls, journaled radially to it, saidwiping-rolls being provided with rubber. or other flexible ribs to fitthe top of the can, pinions on the wiping-rolls, and a friction or other gear acting on said pinions and rotating in an opposite direction from the fly-frame, inner and outer concentric sleeves to which are at-. tached the gean and the. fly-frame, respectively, and band-pulleys attached to said sleeves. These parts rotateabout a vertical a plug for entering the mouth of the can. The wiping action of my machine is thus twofold-the fly-frame having a centrifugal motion which tends to throw outward theliquid taken up by the flanges on the wipingrolls, and the rotary motion of the wipingrolls themselves which tend to throw it upward and outward.

My invention consists of the various combinations of elements set forth in the claims.

I illustrate my invention by means of the accompanying drawings, in which Figure l is a perspective view of afinachine embodying my invention. Fig. 2 is a vertical section. Fig. 3 is a view from 1111* derneat-h, and Fig. 4: is a detail of the wiping-- roll.

Serial No. 302,808. (No model.)

The machine is mounted on a table or bench A by means of a standard G, having a horizontal arm at its upper end, to which is secured the fixed vertical shaft II, having on its lower end a plug I, whose lower end is tapered to move readily into the mouth of the can. Through this plug there are vents tfor relieving any excess of air in the can.

Resting on the plug is the collar J, which acts as a bearing for the inner sleeve L, fitting the shaft I-I. Extending out from the lower end of the sleeve L are the radial arms P, which support an annular gear, here shown as a friction-gear, though it is obvious that it may be a tooth-gear. Secured to the .top of the sleeve L is a band-pulley Q. Fit- .ting outside of the sleeve L is an outer sleeve P, to the lower end of which is connected what I here ca l the fly-frame L.

It has radial arms and an'annular rim of greater diameter than the can, which rim extends outside of and beneath the gear or rim P. In this rim are formed the bearings Z and Z, in this case four sets, in which are journaled the wiping-rolls N, extending radially inward and having their inner ends reaching to the plug I. These rolls are each composed of an arbor n, on the end of which is the roll proper, which is made of some what larger diameter on its inner end than on its outer. The rolls, when in position, are directly over the annular top of thecan and extend from the mouth-to the edge. Each roll, as here shown, is formed in one piece, and it-has two longitudinal slots cut init at right angles to each other, these slots extending from the end back to thearbor. In these slots are inserted the rubber flanges n in two pieces, each piece having two operating-edges, as shown in Fig. 4. All the parts of the roll are held firmly in place by the single screw n passing through two opposite segments.

To the fly-frame L is attached one or more ribs or wings L which fit more or less perfectly the casingR by which the parts are inclosed. This casing R has an opening in one side leading tangentially out from it, and thence communicating with a vertical pipe R, by which the liquid, &c., taken from the top of the can is carried away.

i On the arbor at there is a pinion 0 (here i shown as a friction roll or pinion) adapted to engage with the friction-gear P, although it may equally well be an ordinary toothed pinion.

Clamped in the upright G there is a hori zontal arm Z), adjustable longitudinally, and on the end of this arm is the centering-guide F, by which the cans E are centered beneath the wiping-gear. The can rests, when in position, on a base or rest B, which is raised to bring the top of the can in contact with the wiper. \Vhen at its lower position, it is flush with the surface of the table. \Vhen down, the base B rests on a cross-piece 0, through which passes the vertical stem b, to the upper end of which the base B is secured. A vertically-adjustable stop or collar b is secured to the stem 1) by means of a set-screw 11 A foot pedal or lever D is provided beneath the table to raise and lower the base B.

The operation of my wiper is as follows: The can being placed on the base B, the treadle D is depressed and the can raised until the stop 19 strikes against thecross-bar 0, when the top of the can will be brought in contact with the rolls N. The two band-pulleys Q and Q are rotated in opposite directions, and, as a consequence, the friction-gear P and the fly-frame L movein contrary direct-ions. The gear P thus turns the pinion 0, making the rolls N rotate very rapidly. As a result the liquid or other substance which has collected on the surface of the can will be swept away and forced against the side of the casing, whence it Will be taken to the pipe R by the wing L and carried away.

It will be observed that there are two motions, both tending to clean the top of the can, one being the centrifugal motion caused by the rotation of the fiy-frame and the other the scouring effect of the revolving wipingrolls.

It is evident that the flexible ribs of the wiping-rolls may be replaced by flexible pins or other similar devices which will have a scouring effect.

I claim 1. In a machine for wiping cans, the combination of a rotating fly-frame and rotating wiping-rolls journaled radially thereto, sub stantially as described.

2. In a machine for wiping cans, the combination of a rotating fly-frame, rotating wiping-rolls journaled radially thereto, and flexible flanges secured longitudinally to said rolls and adapted to lit the top of said can, substantially as described,

3. In aean-wiping machine the combination of a rotatingfly-frame and rotating wiping-rolls journaled in the outer edge or rim thereof and extending inward over the top of the can, substantially as described.

4:. In a can-wiping machine, the combination of a rotating fly-frame, wiping-rolls journalcd radially thereto, a pinion secured to each of said rolls, and a tootlrgear for engaging said pinion and rotating the same, substantially as described.

5. In a can-wiping machine, the combination of a vertical shaft, a plug secured to the lower end thereof and adapted to enter the mouth of the can, and a fly-frame rotating about said shaft and having wiping-rolls journaled to it, the inner ends of said rolls extending to or nearly to said plug, substantially as described.

6. In a can-wi ping machine, a vertical shaft, a plug or stop secured to the lower end there of, an inner sleeve fitting said shaft and having at its lower end a gear, an outer sleeve fitting said inner sleeve and having at its lower end a fly-frame with wiping-rolls journaled thereto, and pinions on said wipingrolls adapted to engage said gear, substantially as described.

7. In a can-wipin machine, a vertical shaft, a plug or stop at its lower end, an inner sleeve fitting said shaft and having at its lower end a gear, an outer sleeve fitting over said inner sleeve and having at its lower end a iiy-frame with wiping-rolls j ournaled thereto and adapted to engage said gear, and pulleys for said outerand inner sleeves, whereby they are rotated in opposite directions, substantially as described.

S. In a can-wiping machine, a fly-frame, a casing surrounding it and a passage leading tangentially therefrom, and a rib or wing on said fiy-fralne filling or nearly filling said casing, whereby all liquid is carried to said passage, substantially as described.

In testimony whereof I affiX my signature in presence of two witnesses.
